This newsletter provides a concise 7-, 14-, and 21-day US weather summary focused on factors affecting restaurant operations, including severe weather risks (tornadoes, storms), extreme temperatures impacting HVAC efficiency and energy use, and potential disruptions to supply chains, outdoor seating, or foot traffic.

Current & 7-Day Outlook (May 4-10, 2026)

• Severe Weather/Tornado Risks: Marginal to Slight Risk of severe thunderstorms across parts of the Midwest and Plains (e.g., Illinois, Missouri, Kansas, Oklahoma). Potential for damaging winds, large hail, and isolated tornadoes, especially May 4-6. No active hurricanes (Atlantic season begins June 1; 2026 outlook below average with 11-16 named storms total). Likelihood of notable tornado impacts in affected cities: 20-30% this week.
• Extreme Temperatures:
  • Above-average warmth (10-20°F+ anomalies in spots) in the South, Ohio Valley, and Mid-Atlantic early week, with highs potentially reaching 80s°F. Cities like Atlanta, Louisville may see records.
  • Cooler than average in northern Plains/Great Lakes. No widespread >95°F highs or <40°F lows expected, but swings could strain HVAC (cooling demand up in South, variable in Midwest). Likelihood of extreme heat (>95°F) or significant anomalies impacting HVAC: 15-25% in southern hotspots.
• Operational Notes: Increased risk of power outages or closures from storms in Midwest/Plains. Warmer conditions may boost outdoor dining but raise cooling costs.

14-Day Outlook (May 11-17, 2026)

• Severe Weather: Elevated thunderstorm activity possible in southern/central Plains and Midwest. Continued tornado watch potential early in period, shifting risks. Likelihood of tornado/severe warnings affecting operations: 25-40%.
• Extreme Temperatures: Enhanced probability of warmer-than-normal conditions across much of the eastern US, Pacific Northwest, and Gulf Coast. Potential for 15°F+ above-average highs in Ohio Valley/Mid-Atlantic. Isolated heat risks in Southwest. Cooler pockets in West Texas. Likelihood of highs >95°F or anomalies ≥15°F impacting HVAC: 30-45% in favored warm areas.
• Operational Notes: Higher cooling demand in East/South could increase energy costs; monitor for heat-related staff/guest comfort.

21-Day Outlook (into late May 2026)

• Severe Weather: May remains peak tornado month; risks concentrated in Plains/Midwest. Hurricane landfall probability low early season (overall US major hurricane landfall ~32% for full 2026 season). Likelihood of disruptive events: 35-50% cumulative.
• Extreme Temperatures: Ridging favors above-normal temps in East, PNW, and Gulf. Possible heat buildup in Southwest. Likelihood of extreme temps/anomalies affecting HVAC efficiency: 40%+ in southern/eastern states.
• Operational Notes: Plan for sustained higher cooling loads; prepare for variable spring-to-summer transition.

Key Cities/States to Watch:

• Tornado/Storm Risks: Oklahoma City, Dallas, St. Louis, Chicago areas (highest short-term).
• Heat/HVAC Strain: Southern states (TX, FL, GA), Mid-Atlantic, Southwest (e.g., Phoenix potential records).
• Cooler Impacts: Northern Plains, Great Lakes (variable HVAC).
